Here are the operation goals for that plan:

THE NAKED COMMUNIST: 45 COMMUNIST GOALS

On Jan. 10, 1963, Congressman Albert S. Herlong Jr. of Florida read a list of 45 Communist goals into the Congressional Record. The list was derived from researcher Cleon Skousen’s book “The Naked Communist.” These principles are well worth revisiting today in order to gain insights into the thinking and strategies of much of our so-called liberal elite:

U.S. should accept coexistence as the only alternative to atomic war.
U.S. should be willing to capitulate in preference to engaging in atomic war.
Note: These encapsulate the Kennan Doctrine, which advocated for the "containment" of communism. Establishment figures supporting the amoral containment policy at least implicitly worked with the communists in scaring the wits out of the American people concerning atomic war. President Ronald Reagan undid the doctrine when he took an aggressive stand against the Evil Empire by backing freedom fighters from around the world that were struggling against the left-wing communist jackboot. As a result, the Soviet Union and its satellites imploded, a considerable and unexpected setback to the international communist edifice.
Develop the illusion that total disarmament by the U.S. would be a demonstration of "moral strength."
Note: The nuclear freeze advocates supported a freeze on American nuclear development only. Rarely were Soviet nukes or those of other nations mentioned in their self-righteous tirades. The same advocates now call for reducing American military might, claiming that there is something immoral about America preserving its military pre-eminence in the world.
Permit free trade between all nations regardless of Communist affiliation and regardless of whether or not items could be used for war.
Note: Today, there are calls to end the embargo on the slave island of Cuba, there were complaints about the embargo against Iraq, and the U.S., not Saddam Hussein, was blamed for the suffering of the Iraqi people. Would they have advocated for free trade with Hitler and his National Socialist regime?
Extend long-term loans to Russia and Soviet satellites.
Provide American aid to all nations regardless of Communist domination.
Note: Such aid and trade over decades contributed greatly to the left-wing communist liquidation of over 100 million people worldwide, according to the well-documented "Black Book of Communism." This aid and trade marks a shameful chapter in American history. Without the aid and trade, the left-wing international communist behemoth would have imploded on its own rot a lot sooner and umpteen millions would have been saved from poverty, misery, starvation and death.
Grant recognition of Red China and admission of Red China to the U.N.
Note: Not only did President Jimmy Carter fulfill this goal but he also betrayed America’s allies in Nicaragua, El Salvador, Iran, Afghanistan, Angola and elsewhere.
Set up East and West Germany as separate states in spite of Khrushchev's promise in 1955 to settle the Germany question by free elections under supervision of the U.N.
Prolong the conferences to ban atomic tests because the U.S. has agreed to suspend tests as long as negotiations are in progress.
Allow all Soviet satellites individual representation in the U.N.
Promote the U.N. as the only hope for mankind. If its charter is rewritten, demand that it be set up as a one-world government with its own independent armed forces.
Note: There are still American intellectuals, and elected members of Congress, who dream of an eventual one world government and who view the U.N., founded by communists such as Alger Hiss, the first secretary-general, as the instrument to bring this about. World government was also the dream of Adolf Hitler and J.V. Stalin. World government was the dream of Osama bin Laden and the 9/11 hijackers.
Resist any attempt to outlaw the Communist Party.
Note: While the idea of banning any political party runs contrary to notions of American freedom and liberty, notions that are the exact opposite of those held by the left-wing communists themselves, nevertheless these goals sought to undermine the constitutional obligation of Congress to investigate subversion. The weakening of our government’s ability to conduct such investigations led to the attack of 9/11.
Do away with loyalty oaths.
Note: It is entirely proper and appropriate for our government to expect employees, paid by the American taxpayer, to take an oath of loyalty.
Continue giving Russia access to the U.S. Patent Office.
Capture one or both of the political parties in the U.S.
Note: In his book, "Reagan’s War," Peter Schweizer demonstrates the astonishing degree to which communists and communist sympathizers have penetrated the Democratic Party. In his book, Schweizer writes about the presidential election of 1979.
Use technical decisions of the courts to weaken basic American institutions, by claiming their activities violate civil rights.
Note: This strategy goes back to the founding of the American Civil Liberties Union by Fabian Socialists Roger Baldwin and John Dewey and Communists William Z. Foster and Elizabeth Gurley Flynn among others.
Get control of the schools. Use them as transmission belts for Socialism and current Communist propaganda. Soften the curriculum. Get control of teachers associations. Put the party line in textbooks.

From “The Naked Communist” by W. Cleon Skousen

Back in the early part of the 20th Century Russia produced some of the most brilliant and influential social scientists and psychologists in the world.

The Soviets exploited these scientists and psychologists to further their goals of Communist subversion and revolution

The generation of social scientists and psychologists were given the ability to observes and experiment on Russians who were caught up inn the Soviet reign of terror and then horrors of WWII with absolutely no regard for ethics, human rights and especially no regard for human life.

Many of their research subjects were victims of the Stalinist purges, show trials and gulags and the Soviets learned well the science of how to manipulate and control people as well as how to use stress, coercion, death threats and propaganda modify people behavior and alter their thought processes to conform to those officially sanction by the Soviet government.

In the WWII era and for the decade or so post WWII when the USSR help German POWs , many of the brain washing and behavior modification experiments were done on German POWs in the gulags with absolutely no constraints or ethical / human rights considerations which they then implemented and expanded on to solidify their control of the Warsaw Pact nations and East Germany .
